Longtime watch maker Casio announced a new sports watch using Bluetooth 4.0 technology so owners can check personal fitness data wirelessly - and control a smartphone's music player directly from the watch. The STB-1000 includes Apple iPhone compatibility, Bluetooth 4.0, and third-party iOS fitness apps, such as Wahoo Fitness and Abvio Runmeter.

"This is an ideal sports watch for countless recreational runners who exercise with their iPhones," said Shigenori Itoh, Casio America CEO, in a statement. "In addition to the compatibility with several apps, it has a battery life up to two years and a versatile, water-proof design that makes it easy to use and wear before, during and after any workout."

The watch will run for around two years with a single battery, and doesn't require frequent recharging like many sport watch and GPS units.
